Bicycle is not only a means of transportation, but also a "fitness equipment" for many people. There are more and more bicycle colors on the market, which meet the aesthetic needs of different people. The bicycle tire is no longer a single black, red, green, yellow, beige, and so on. Most bicycle tyres are processed with natural rubber, natural rubber/styrene-butadiene rubber as the main raw materials; Latex reclaimed rubber is recommended to select appropriate natural reclaimed rubber when it is used to reduce the cost of raw materials for bicycle tyres.

1. Select latex recycled rubber according to the color of bicycle outer tire

Green bicycle tire

The bicycle cover is colorful, and the latex recycled rubber with the same color as the bicycle cover is selected. The color matching is easy and not easy to change color during the processing, and the color matching cost is lower. At present, the latex reclaimed rubber 2SLYY224 on the market is mainly white latex reclaimed rubber and black latex reclaimed rubber. There are also some color latex reclaimed rubber, such as red latex reclaimed rubber and green natural reclaimed rubber. For example, green latex reclaimed rubber can be used for green bicycle outer tire.

2. Select the latex reclaimed rubber according to the mechanical performance index of bicycle tire

The physical and mechanical properties of the rubber used for the bicycle outer tire in different applications are different, including the tensile strength, tear strength, elongation at break, permanent deformation, constant elongation stress, hardness, resilience, etc., to ensure that the bicycle outer tire has good wear resistance, safety, puncture resistance, tear resistance, etc. When the bicycle outer tube is mixed with latex recycled rubber, it is recommended to select the product that is close to the technical index of the outer tube, and use black latex recycled rubber for dark and black outer tubes (the price of black latex recycled rubber prepared by the same method is lower than that of white latex recycled rubber), effectively reducing the raw material cost and production cost while ensuring the quality of the bicycle outer tube.

3. It is recommended to select environmentally friendly and non-migration latex recycled adhesive

When using latex reclaimed rubber to produce light-colored and colored bicycle outer tubes, it is recommended to use environmentally friendly latex reclaimed rubber, odorless latex reclaimed rubber, and non-migration latex reclaimed rubber to avoid discoloration, yellowing, and other problems in the process of processing and use of outer tubes, and to avoid producing irritating odor, such as the environmentally friendly natural reclaimed rubber that has passed the ROHS environmental protection directive.

Recycled rubber for light-color bicycle tire

When using latex reclaimed rubber to replace part of natural rubber to produce bicycle tires, the rubber product manufacturer must reasonably determine the replacement parts according to the rubber content of the latex reclaimed rubber, for example, 85% filtered black latex reclaimed rubber shall replace natural rubber according to 1.3: 1; In the later stage, the editor will continue to share with you the key points of formula design, color matching skills, production process, etc. of using latex recycled rubber alone, latex recycled rubber/natural rubber in combination to produce bicycle tires.
